Open-Drain SOT μP Reset Circuit
________________General Description
The MAX6315 low-power CMOS microprocessor (μP)
supervisory circuit is designed to monitor power sup-
plies in μP and digital systems. It provides excellent cir-
cuit reliability and low cost by eliminating external
components and adjustments. The MAX6315 also pro-
vides a debounced manual reset input.
This device performs a single function: it asserts a reset
signal whenever the V CC supply voltage falls below a
preset threshold or whenever manual reset is asserted.
Reset remains asserted for an internally programmed
interval (reset timeout period) after V CC has risen above
the reset threshold or manual reset is deasserted. The
MAX6315’s open-drain RESET output can be pulled up
to a voltage higher than V CC .
____________________________Features
? Small SOT143 Package
? Open-Drain RESET Output Can Exceed V CC
? Precision, Factory-Set V CC Reset Thresholds:
100mV Increments from 2.5V to 5V
? Four Reset Timeout Periods Available:
1ms, 20ms, 140ms, or 1120ms (minimum)
? Immune to Short V CC Transients
? 5μA Supply Current
? Pin-Compatible with MAX811
? Guaranteed Over Temperature
______________Ordering Information
The MAX6315 comes with factory-trimmed reset thresh-
old voltages in 100mV increments from 2.5V to 5V.
Preset timeout periods of 1ms, 20ms, 140ms, and
1120ms (min) are also available. The device comes in a

? The MAX6315 is available in a SOT143 package, -40°C to
+125°C temperature range.
?? The first two letters in the package top mark identify the part,
while the remaining two letters are the lot tracking code.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
Note: All devices available in tape-and-reel only. Contact fac-
tory for availability.
